The demand came after Spotify removed a number of artists last week as they instituted a new hate content policy aimed at refusing exposure to those with a history of abusive behavior.

“Thank you for taking the important first step of removing infamous abusers R. Kelly and XXXTentacion from your official playlists,” said UltraViolet executive director Shaunna Thomas in an open letter on Spotify chief Daniel Ek. “On behalf of our 1 million members, UltraViolet applauds and supports this choice. Yet as you know, these two men are not the only abusers on your platform. We implore you to take a deeper look at the artists you promote.”

Citing the four rock artists among a “nowhere near” comprehensive list, she added, “Every time a famous individual continues to be glorified despite allegations of abuse, we wrongly perpetuate silence by showing survivors of sexual assault and domestic violence that there will be no consequences for abuse. … We publish this as an open letter because we hope other platforms like iTunes, Google Play Music and Pandora will continue to follow your lead.”

In a 2017 essay, Consequence of Sound listed some acts of misconduct that “have long existed in the public domain,” including Tyler’s guardianship of a 16-year-old girl whom he got pregnant when he was 27 and Chili Peppers singer Anthony Kiedis’ sexual relationship with a 13-year-old girl when he was 23. TheWeek.com recounted last year how Henley was fined and put on probation in 1980 after being found with two underage girls who were charged with drug and prostitution offences, and how, in 1978, Nugent faced kidnapping charges in connection with a 17-year-old girl when he was 30.
